| Abstract: | The properties of the immobilized microbial cells whieh were prepared byimmobilizing the aspatase containing escherichia coll as 1.818 with polyvinylalcohol(PVA)as asupporter were studied by various methods,The storage and usage stabiliyt of the immobilized cellswas much higher than that of the intact cells.The immobilized aspartase could be used for thecontinuous and the intermittent production of L-asparic acid from ammonium fumarate. |
